Physics: Projectile Motion

Front

What is a vector?

Back

A vector is a quantity that has both magnitude (size) and direction.

Front

What does the length of a vector represent?

Back

The length of a vector represents its magnitude.

Front

What does the direction of a vector indicate?

Back

The direction of a vector indicates the direction of motion.

Front

What is projectile motion?

Back

Projectile motion is the motion of an object thrown into the air, affected only by gravity and its initial velocity.

Front

What happens to the horizontal component of a projectile's velocity in the absence of air friction?

Back

It remains constant as the projectile moves.

Front

What is an example of a projectile?

Back

A cannonball thrown in the air is an example of a projectile.

Front

Which of the following is NOT a projectile?

Back

A cannonball rolling down a slope is NOT a projectile.

Front

True or False: The orientation of a vector shows the direction.

Back

True.

Front

True or False: The length of the vector represents magnitude.

Back

True.

Front

What is the effect of air friction on projectile motion?

Back

Air friction can slow down the projectile and alter its path.
